2:33pm

ukrainian people. it would be a clear violation of russia's commitment to respect the independence and sovereignty and borders of ukraine and of international law. just days after the world came to russia for the olympic games, condemnationte the of nations around the world, and indeed, the united states will stand with the international community in affirming there will be costs or any military intervention in ukraine. said any's ambassador military movement his country is making is in keeping with moscow's existing agreements with ukraine. >> crimea's main connection to theoutside world today in hands of men with machine guns. they wore no insignia, but their military fatigues were russian designed. there weapons were russian standard issue.

2:35pm

many are suspicious of the new government and supported the russian move. >> who else can we turn to? who can defend us? thank goodness the russian fleet is here to defend us. >> this russian naval ship appeared in the interest -- the entrance to the world-famous pollock llama bay, another show of strength our armed forces. >> ukraine has lost control of the seas around crimea and its main airports, but the acting president said he would react carefully. >> i appealed personally to president putin to immediately stop provoking us. from crimea and cooperate by sticking to agreements already signed between us. >> across the border in russia, ousted he replaced,

2:36pm

president viktor yanukovych, appeared in public for the first time since he fled last week. ukraine has asked russia to hand him over as a suspect, but he seemed affiant -- defiant. >> i am eager and ready to fight for the future of ukraine. i was forced to leave, and there were threats to my life and to people close to me. power was taken by nationalists and fascists, who are in the minority in the ukraine. >> these cameras show the moment the regional parliament was stormed yesterday by men with machine guns and rocket propelled grenades. the tv station was also taken today. evis is not yet a war, but ki has not moved to reassert control, and if it does, moscow made it clear today that its troops are waiting.

2:37pm

>> a brief time ago, i spoke with daniel sanford in the crimean city and started by asking how he thought president obama's comments on ukraine .ould be received >> i don't think people in crimea will be particularly , but those that support the russian move will feel fairly confident tonight that their fate is in russian hands. i think russians at the moment to hold all the cards in crimea. there's nothing very much that the ukrainian government in kiev about the situation. they cannot really come charging down the troops because that is almost certain to provoke a conflict. i think at the moment, the russians can sit tight and see what happens next and then into negotiations further down the line. >> how are people where you are responding to the presence of these forces loyal to russia on the street? dangerous tos generalize about these types of things, but there are certainly large numbers of russian

2:38pm

speakers who feel very strong links to russia and were very worried when the new government came to power in kiev supporting these far right activists, and we are very concerned that the far right activists would dissent here. that may have been a false concern, but it was a genuinely felt concern. but there are other groups here who are very supportive of the kiev government. crimean's are also very distrustful. they were thrown out of crimea during the soviet union, but many trickled back during the 1990's. but there are many people here who are very worried about what is going on. but i think the majority are either sitting on the fence or supportive of the russian move. >> viktor yanukovych and that rather lengthy press conference today condemned what he called the bandit two -- bandit coup. what have people been saying about his appearance? >> everyone here has been

2:39pm

focused on the military movement. but to be honest, with such crimeay scenes here in with trucks driving up another road, attack helicopters flying overhead and ships blockading port, viktor yanukovych's comments pretty much went unnoticed. >> in other news now, a court in placing the opposition leader under house arrest for violating travel restrictions. he says these charges are politically motivated. he will no longer be allowed access to a phone on the internet under the ruling. exchange hasrrency filed for bankruptcy protection in japan. it went off-line earlier this week. it now says hundreds of worthnds of bitcoins several hundred million dollars are unaccounted for. crime agencies worldwide have carried out what is believed to be the biggest operation against gangs suspected of tricking

2:42pm

thatwe have shown here is we are able to do that as well. >> back in barcelona, five people were taken away to join more than 100 others arrested in the simultaneous raids. this scam has not been , but it will offer reassurance to victims and severely damage the boiler room's ability to operate. >> quite the scam there. the world bank, one of the biggest providers of aid to uganda, has postponed a $19 million loan to the country following a new law imposing harsh punishments on gay men and women. homosexual acts were already illegal in uganda. those convicted could face life imprisonment. the government said the world bank's move amounted to blackmail. >> this week, uganda proclaimed to the world it will not change its anti-gay culture for anyone.

in this country, the message from the government is to hide it or feel the heavy hand of the law. the president unusually called a press conference to sign the bill into law, a very public act of defiance ignoring warnings from president obama, who called the plans morally wrong. are right behind their president. culture.t support gay it spreads disease. it is a deeply religious and conservative country. some lawyers say even media this one talking open about homosexuality could be seen as promoting it, which could carry a prison sentence of up to seven years. >> uganda's health system is heavily reliant on foreign donors. the u.k. suspended direct aid to .he country last year

2:44pm
